Simulated electric field distributions of plasmonic dipolar resonant modes supported in T-shaped antenna under linear polarization excitations at normal incidence (a) at the plasmonic resonance of horizontal arm λ 1 = 1375 nm along the x-polarized direction, (b) at the plasmonic resonance of vertical arm λ 3 = 1850 nm along the y-polarized direction, and (c), (d) at the crossing point of transmission amplitude spectra along both polarized directions.
